AS5115 Demoboard OPERATIONAL MANUAL

OTP tab
The OTP tab is normally used for the AS5000 programmer, but the OTP bits can be changed on the AS5115 demoboard as
well.
Options like gain and Hall bias can be changed by selecting the function in "Fields", then changing the parameter in "Options
for the selected field" or directly the decimal value of this parameter in "Value".
Each time a field's value has been changed, the corresponding OTP bits will be automatically checked in the right window.
The button Write should be clicked to write the parameter into the AS5115.
The Read button reads back the OTP register, and updates the "Field" parameter as well as the OTP bits window.
Field Gain: Sets the gain of the internal signal path.
-
0: Sensitivity = 1.65
-
1: Sensitivity = 1.88
-
2: Sensitivity = 2.11
-
3: Sensitivity = 2.35
Field Hall Bias: To change the Hall Bias current:
-
0 – 63: depending on the desired output voltage
Note that the Zap! button is used for the AS5000 Programmer only and has no effect on the AS5115 Demoboard.
